concatenation in c++ string code example
Example 1: concat string in c++
#include <iostream>
#include <sstream>
int main() {
std::string value = "Hello, " + "world!";
std::cout << value << std::endl;
std::ostringstream ss;
ss << "This is an integer" << 104;
std::cout << ss.str() << std::endl;
}
Example 2: how to merge string array in C++
For string concatenation in C++, you should use the + operator. std::string nametext = "Your name is " + name; where operator + serves to concatenate strings. nametext is an std::string but these do not have the stream insertion operator ( << ) like output streams do.
